Summary of Changes

Hello @boikoa-gl, I'm Gemini Code Assist1! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request introduces a new Firebase Phone Number Verification (FPNV) module into the Firebase Admin SDK. This feature enables developers to verify phone number tokens, similar to how existing ID tokens are handled. The changes involve adding the necessary service classes, integrating them into the SDK's public API and build configuration, and establishing robust token verification logic, including custom error handling and support for the ES256 JWT algorithm.

Highlights

  • New FPNV Module: Introduced a new Firebase Phone Number Verification (FPNV) module to the SDK.
  • SDK Integration: Integrated the FPNV service into the Firebase Admin SDK's public API, including entrypoints.json, package.json exports, and the firebase-namespace-api.ts.
  • Token Verification Logic: Added core logic for verifying phone number tokens, including decoding, content validation, and signature verification using FirebasePhoneNumberTokenVerifier.
  • Error Handling: Implemented dedicated error handling for FPNV operations with the new FirebasePnvError class and FpnvErrorCode definitions.
  • ES256 Algorithm Support: Extended JWT verification utilities to support the ES256 algorithm.

Code Review

This pull request introduces a new fpnv (Firebase Phone Number Verification) service. The overall structure is good and follows the existing patterns in the SDK. However, there are a few critical issues that need to be addressed before merging. The error handling for this new service is incomplete, with placeholder error codes in FpnvErrorCode. This will lead to incorrect error reporting. I've provided a suggestion for a more complete implementation. There's also a potential bug in the JWT audience (aud) claim verification that could cause a runtime error. Finally, I've made some suggestions to use more specific error codes to improve the developer experience. Please review the detailed comments.
